1. An air flow deflector assembly for a thrust reverser system of an engine of an air vehicle, the air flow deflector assembly comprising:

  • an air flow deflector apparatus movable between a stowed non-reversing position and a deployed thrust reversing position, wherein the air flow deflector apparatus comprises a deflector barrier panel configured to block a reverse efflux air flow;

    one or more extender rods, each having a first end coupled to the air flow deflector apparatus;

    a recessed housing disposed in a surface of a nacelle of the engine, the recessed housing having a length that is greater than a combination of a length of the air flow deflector apparatus and a length of the one or more extender rods; and

    an air flow deflector actuator comprising an actuating portion coupled to a second end of each of the one or more extender rods and coupled to the recessed housing,wherein the air flow deflector assembly is configured to deflect an air flow out of the engine, and to provide an effective reverse thrust for the thrust reverser system, and further wherein the air flow deflector assembly is positioned at a location of the nacelle that is forward of a plurality of cascade members of the engine, and that is downstream of a thrust reverser bullnose fairing.
